logstash_curator incompatible with curator 3 commands

[jrstarke]

I recently built a new logstash server using this cookbook. As part of my recipe, use logstash_curator to cleanup old logs. This LWRP creates a new cronjob on the logstash user that runs

/usr/local/bin/curator --host 127.0.0.1 delete --older-than 6 &> /dev/null

I found that my disk space was running high, so I attempted to run

/usr/local/bin/curator --host 127.0.0.1 delete --older-than 4 &> /dev/null manually. After running this a number of times with no results, I dropped the&> /dev/null` and found I was getting an error

Error: no such option: --older-than

Check your elasticsearch-curator python module version. New curator version (> 4.0.X) use new strategy and configurable by .yml config files.
